The caldera and most of the park are located in the northwest corner of Wyoming. The caldera measures 43 by 28 miles 70 by 45 kilometers , and postcaldera lavas spill out a significant distance beyond the caldera proper. The caldera formed during the last of three supereruptions over the past 2. The caldera was the largest known until the discovery of Apolaki Caldera in , which is more than twice as wide. Volcanism at Yellowstone is relatively recent, with calderas created by large eruptions that took place 2. The calderas lie over the Yellowstone hotspot under the Yellowstone Plateau where light and hot magma molten rock from the mantle rises toward the surface. The hotspot appears to move across terrain in the east-northeast direction, and is responsible for the eastern half of Idaho 's Snake River Plain , but in fact the hotspot is much deeper than the surrounding terrain and remains stationary while the North American Plate moves west-southwest over it. Over the past Together these eruptions have helped create the eastern part of the Snake River Plain to the west of Yellowstone from a once-mountainous region. Volcanic eruptions sometimes empty their stores of magma so swiftly that the overlying land collapses into the emptied magma chamber , forming a geographic depression called a caldera. The oldest identified caldera remnant straddles the border near McDermitt, Nevada—Oregon , although there are volcaniclastic piles and arcuate faults that define caldera complexes more than 60 km 37 mi in diameter in the Carmacks Group of southwest-central Yukon , Canada, which are interpreted to have been formed 70 million years ago by the Yellowstone hotspot. One such caldera, the Bruneau-Jarbidge caldera in southern Idaho , was formed between 10 and 12 million years ago, and the event dropped ash to a depth of one foot 30 cm 1, miles 1, km away in northeastern Nebraska and killed large herds of rhinoceroses , camels, and other animals at Ashfall Fossil Beds State Historical Park.
